Remove any really bad leaves. And then I spray with my bottle of 1:3 peroxide all over the leaves. And do this every few days.

I had powdery mildew on a flaming Katy a few months ago. First, I pruned the worst affected leaves. Then I mixed up a recipe of 1 tablespoon baking soda and 1/2 teaspoon dish soap to a gallon of water (I used chatGPT to scale the recipe down for me since I knew I wouldn’t need that much.) I sprayed that on the leaves once a week for 4 weeks. After the final week, I wiped all the leaves off with a wet paper towel and it was cured. I know some recipes will call for neem oil and other fungicides, but this worked just fine for me. Hope this helps!

Don’t be afraid to get brutal with the pruning, but it only looks like you have a few that you need to get rid of. Good luck!
